That's a really important point, and I think it's one of the main points of resistance to the MPA concept in general, at least among fishermen in our area.
Fishing activity, the productivity of different fisheries, is constantly changing in this area. When I did my Ph.D. research 32 years ago, there was a lot of similarity in terms of species being harvested, but it has completely flipped. In those years, the weir fishery was doing well, and the lobster fishery and the scallop fishery simply got fishermen through from one season to the next. Now, it's so completely reversed. The lobster fishery is completely dominant and is just unbelievably lucrative.
